working principle of supercritical boiler

Environmental situation is not optimistic that China has issued a number of environmental policy, the full range of safeguards ecological environment. Provinces are also actively to improve environmental protection, recently, Ningxia Hui Autonomous Region winter heating working principle of supercritical boiler proposed implementation. details as follows.

"Clean heating embodiment of Ningxia Hui Autonomous Region (2018 Year - 2021)," recently released, "plan" put forward, Ningxia heating the status quo, to develop clean heating, the use of clean energy alternative to coal and dispersed living coal, reducing coal consumption and soot emissions, improve environmental quality in urban and rural atmosphere.

By the end of 2017, Ningxia urban and rural housing construction for heating a total area of ​​380 million square meters, of which the city building heating area of ​​about 240 million square meters, rural buildings for heating an area of ​​about 140 million square meters. Clean heating total area of ​​about 180 million square meters, accounting for about 47% of the region's total heating area. Among them, prefecture-level city clean heating an area of ​​about 120 million square meters, clean heating rate of about 75%; counties (cities, districts) Clean heating an area of ​​about 50 million square meters, clean heating rate of about 62%; rural clean heating area of ​​about 14.72 million square, clean heating rate of about 10%.

After the "plan" put forward, Ningxia, according to the "central heating mainly to the substitution of gas for coal as the first, supplemented by electricity instead of coal," the idea, according to local conditions, scientific planning, coordination implementation. City, county (district) the main city clean coal-fired co-generation, large-scale energy saving boiler central heating heat source as the basis for strengthening efforts to shut down within a small range of central heating boilers of coal. Promote cogeneration units and ultra-low emissions transformation of large boilers, improving the environmental standards.

In urban and rural interface and rural areas, in accordance with the principles of the easier issues first, and start cleaning centralized heating schools, kindergartens, hospitals and other public buildings start to play an exemplary role. The conditions of the area to promote gas boiler; encourage nearby collected plant biomass feedstock, biomass briquette forming process instead of bulk coal; encourage livestock waste, straw and other raw material for the biogas fermentation and purified, for clean heating; actively promote the development of geothermal resources as a centralized or decentralized heating heat source; support for residents to install solar hot water, electric heating equipment, such as housing, agriculture greenhouses, farms; do not have clean heating conditions actively implement clean coal alternative bulk coal.

"Plan" clearly, Ningxia will accelerate cogeneration, waste heat utilization, the cell set into a piece of construction heating boilers, focusing on the completion of the Western Xia thermoelectric (two) central heating, in Nanjing Tianyuan thermoelectric, Helan back pressure Heating Unit central heating and other projects, the completion of thermoelectric Zhongwei, Wuzhong thermoelectric, thermoelectric Dawukou LIUPANSHAN thermoelectric renovation project, to further expand the central heating area. City, county (district) heating should vigorously promote the "coal to gas," "coal to electricity", according to local conditions the development of renewable energy for heating, a pair of old, energy-saving secondary pipe network, heating network system to enhance efficiency.

Ningxia will be fully phased out small coal-fired boilers, coal-fired boiler to deepen the comprehensive compliance management, municipalities, county (district) urban area out of 20 tons of steam / hour coal-fired boilers. Yinchuan City urban area to total phase-out project cogeneration district heating pipe network covering all coal-fired heating boilers in the region. It does not have the "coal to gas," "coal to electricity" conditions in rural areas, to achieve clean coal production and warehouse distribution center full coverage, full implementation of clean coal alternative bulk coal.

Ningxia Hui Autonomous Region in the 2018-2021 four-year, with the full complement of winter heating boiler, will replace all cleaner energy boiler coal-fired boiler, to protect people's health.

Temperature Regulation of outlet Water of Hot Water Boiler

According to the local conditions, the boiler use unit formulates the relationship between the boiler outlet water temperature and the outdoor air temperature. In the operation, according to the corresponding relationship between the specified outlet water temperature and the outdoor air temperature, the combustion amount is adjusted in time, and the water supply temperature of the network management system is required to be different from the specified temperature. 120 ° C. The change of water supply temperature should be carried out step by step, and the water temperature increase or decrease should not exceed 20 °C.

Henan local fast energy secondary gas steam working principle of supercritical boiler using the principle of utilizing thermal energy, scientific combustion collector configuration, to replace the traditional steam boil cabinet structure, since the collector combustion compact structure. Fuel combustion thermal efficiency up to 93%. Using high-quality stainless steel, heat quickly, corrosion turbid, high quality insulation measures the outside, so that the inner tank in a short time to reach the vaporization temperature, outlet steam temperature up to 110 degrees, continuous automatic water inlet means continuously vaporized. Structure than the conventional boil under the same conditions of use efficiency of 40% to 60% energy. Whole configuration automatic control circuit, including hydraulic, pneumatic, gas, water slightly during operation of the abnormality, the machine automatically cut off the gas inlet valve.

What existing food factory working principle of supercritical boiler energy conservation problems of food plant boiler energy conservation issues What? Food factory boiler and people's lives, the use of food in boiler plants, energy consumption and pollution emissions from the boiler plant food are large. On the city's pollution, contaminated food plant boiler in the first place. It must be a reasonable analysis of the energy-saving and emission reduction in food plant boiler problems and propose measures to better promote the development of food factory boilers. 1, boiler energy conservation status of plant food with the rapid economic development, China's food plant boiler has also been a rapid development, food technology plant boiler has been significantly improved, and promote economic development. But the development of food factory boilers, boiler plants for the food situation is more serious waste of resources, cause great environmental pollution. With the enhancement of the level of people's lives, the concept of environmental protection has also been strengthened. As society progresses, people for energy saving, environmental protection, more and more attention to food production plants is increasingly demanding requirements of the boiler. In the current stage, China's technological level of food plant boiler low, relatively large in terms of energy consumption, low on energy utilization, serious waste of resources, for energy conservation, food factory boilers caused some impact. 2, there is the food plant boiler energy conservation issues in low levels of self-control 2.1 boilers Food Factory, Furnace package is a very important part of the machine supporting the furnace is to achieve feeding, fire, burn, burn foundation to ensure, it is also the underlying hardware energy saving. At this stage, China's level of self-control food factory boiler is low, the change can not be done with energy and automatically adjusts the boiler operation carried out in accordance with the outside world. Also with degrees in the main and auxiliary engines is not high, related instrumentation equipment failure during operation, leading to relevant key operational data can not be very good grasp, can not be health food factory to be a good grasp of the boiler.
